The TS8002 is a split-rail power Class-G power management IC optimized to work with the TS8001 Audio Amplifier. The combination of the TS8001 and TS8002 maximizes battery life by automatically varying the configurable supply voltages for the headphone amplifier based on the audio signal level while delivering high-fidelity audio. The two-chip implementation minimizes power supply noise coupling. The true-ground “Capless” output implementation eliminates the need for large external DC-blocking capacitors between the audio amplifiers and the headphone loads to save board area, reduce cost, and improve low frequency audio fidelity.
